grafana: 8.4.5 -> 8.4.6

No-op release: https://github.com/grafana/grafana/releases/tag/v8.4.6

Yes, this is actually not really needed since we only provide the OSS
version of Grafana and the CVE in question is only exploitable on
Grafana enterprise, but I decided to perform this update to test the
update script I previously implemented in 7708fccf01.
